Nui was a great host. He is professional and helpful. The house is very clean and and beautifully furnished. Internet is decent. The bed and the couch is comfy. There is an ironvfor your clothes, which proved very useful to me.
The building is 5 minute walk from Phra Kanong BTS station, which directly goes to central station Siam, where all the malls are and where you can connect to all the other places of interest. There is a small grocery next to building's entrance for any needs, a small and a bigger 7-Eleven stores few meters away, and few food stalls just outside of the building, but to stay on the safe side, I recommend going to Tesco Lotus' Food Court, 15-20 minutes walk away, for clean and cheap local food.
